Drop by Drop houses plants under a glass dome. Pipes allow water to be added in to be purified, and later collected. The system is designed for grey water – which comes from washing machines, sinks and baths.
A light within the dome triggers the plants to photosynthesise and transpire, so water is drawn through the roots and onto the leaves, where it enters the air as vapour.
A pump controls the system’s airflow and creates a vacuum to further expedite transpiration.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
